No ID

Mike Sergeant of the BBC highlights the plight of stateless refugees:

Mohammed and his sister Maysa are Palestinians, but they have no passports and no identity cards. They are not even given the status of refugees. Legally, they don't seem to exist at all.

They are among about 3,000 so-called "non-ID" Palestinians in Lebanon.

Many don't qualify for aid and have been unable to leave the refugee camps, find jobs or even get married.

"Last year the government prevented me from doing my exams," says Mohammed, a 21-year-old student. "They arrested me because I don't have an ID. Without an ID, I can't do anything."
